How good are the DDP injectors? I was thinking about buying the 150 hp injectors and getting a Valair clutch.

What else would I need to do to hold all of this, and how good is the and support from both companies?

 

They are probly the 2nd or 3rd favorite on the site as being the best. Everyone that has them can say enough good stuff about them. I think you will need a new fuel sysmtem to go with them as they will use some fuel. Add either a pusher pump( holley carter ec.) or go with a walbro , fass, or other new pump setup. After sticks that big you will need a turbo upgrade to see the full potentail from the box and injectors. You get the pic i can keep going too. One thing leads to another and so on. But you will be happy.

 

I have no firsthand experience with them, but there more than a few fellas running the DDP sticks with good results from what I can tell.

 

I just put in some 200hp sticks this Friday. I will be honest with you, I have never ran a differ injector to compare to but these things straight up pull like crazy. However, I did find it quite hard to drive around town without blowing any smoke. If you lug it any whatsoever they will smoke quite a bit. The great thing is that they idle way better than my stock injectors did. I can't wait to see what these do with a bigger turbo.

 

I run some gigantic sized DDP's with TST comp, and smarty, and can drive smoke free with a silver bullet...its all in the turbo for you, a 64 or 66mm will work well, 66 will just have a bit more lag.

I had the 150's long ago, with a JR Adkins HX55, and an edge comp, I made 429hp, without the comp I made 376hp which is 180hp over a stock truck which is about 190hp at the rear wheels.

I love the DDP stuff, but F1 and II make great stuff too. I got turned onto the DDP's when they first came out, they were less than half of what an equal sized Mach would cost, so I gave them a try and they have turned out to be AWESOME.

I have videos of my truck running with both the 200's and the new bigger custom DDP's and you will see the truck makes decent power and hardly any smoke when it spools.

 

I have watched your dragstrip and sledpull videos and they are amazingly clean. Pretty much no smoke at all when spooled. Very nice.

As for the turbo I have pretty much settled on either the silver 64 or the silverbullet. Still not sure which one to go with yet though. I will be doing some sledpulling next year but I also will be driving on the street a lot so I'm kinda thinkin I'll go with the 64.

 

I'm a big fan of DDP injectors. They run very clean, especially with the right turbo.

 

I've been very happy with everything I have from DDP. Their injectors are top notch as well as the service before and after. By far the biggest difference in my trucks performance.

 

I had them in my 01. They will be going in my 12V and my CR.

 

I like my 220's bu does have a little surge at takeoff, never had 150's in ddp had some jammers and liked those as well, jmo ddps are good, and pull hard all the way

 

I love my DDPs. The only thing I don't like about them is when I am cuirsing down the road at 65-70mph in 6th they haze just a little. But at 75mph they run prefectly clean and make great power. I need to check somethings out about the haze, I think it has a small boost leak. I did notice that they run a little cooler going down the road then the injectors that i had in it before.
Hey getblown5.9 how much did it cost to upgrade from the 150s you had to the 200.

 

DDP is a good shop, they will build you some of the best injector available. I'm thinking that 150 sized injector would be a bit hot on a stock turbo and smokey. I have a set of 62liter per minute sticks. They are better than the macher's. My VP doesn't have enough fuel CC's (volume) to feed them. I had a set of 66's, they need a p pump to make them work. The big volume sticks have a funny idle if you pump doesn't supply enough volume. Also you truck will run out of fuel in the injector tubes after a wot pull. That isn't cool, as it will stop running and you have to re-prime the system up, if you don't put the truck into idle and rev her up.
